Pro-independence march takes place in Barcelona

Pro-independence supporters take part in a rally to demand a Catalan government in Barcelona today

Thousands of people have marched in Barcelona to demand the formation of a new government in Spain's Catalonia region leading to its independence from Madrid despite formidable legal obstacles.

Some 45,000 people joined the 'Republic Now' march called by the influential pro-independence citizens' group ANC, city police said.

"There are more than two million of us citizens of Catalonia who want to go forward now, clearly, towards the Catalan republic," ANC vice president Agusti Alcoberro told reporters.

Separatist parties won an absolute majority of seats in the 135-seat Catalan parliament in a snap election on 21 December but have so far failed to form a new government.

Catalonia's two main separatist parties last week proposed a new referendum on a constitution of the "Catalan republic".

The agreement between Together for Catalonia led by deposed and self-exiled regional president Charles Puigdemont and the leftist ERC still needs to be ratified by the small far-left separatist CUP party.

The region of 7.5 million people has been under direct rule from Madrid since Prime Minister Mariano Rajoy dissolved the Catalan parliament last October following an independence referendum not recognised by Madrid.

Debate on the appointment of a new regional president had been set for tomorrow but was postponed indefinitely because the sole candidate, former ANC president Jordi Sanchez, is in jail on sedition charges along with three other separatist leaders.

Mr Puigdemont, who went into self-exile in Belgium, has ruled out his candidacy because of the legal obstacles.

"The fact that today, in the 21st century, there are people in prison for their ideas is a disgrace," Maria Soria, who took part in the march, said.

"It's anti-democratic."
